我无法在模板上进行迭代

Question

我有一个可变字典，其中包含我所有的表格，我想在模板上进行迭代以显示我在词典中拥有的所有表格，而无需像{{example_form}}那样对其进行硬编码，这是我的代码

{% extends 'prescription_menu.html' %}
{% load bootstrap3 %}
{% load crispy_forms_tags %}

{% block title %}Physicians{% endblock title %}

{% block container %}
{% csrf_token %}
<div class="row">
    <div class="col-md-offset-2 col-md-8">
        {% for form in forms %}
            {{form}}
        {% endfor %}

    </div>
</div>
{% endblock container %}

这是我的看法

def UpdatePhysician(request,id):

forms = {}
physician = get_object_or_404(Physician, id=id)
employee = get_object_or_404(Employee, id=physician.employee.id)
person = get_object_or_404(Person, id=employee.person.id)
try:
    address = get_object_or_404(Address, id=return_id(str(person.addresses.values('id'))))
    address_form = AddressForm(request.POST or None, instance=address)
    forms.update({'address_form': address_form})
except:
    address = None
email = get_object_or_404(Email, id=return_id(str(person.emails.values('id'))))
phone = get_object_or_404(PhoneNumber, id=return_id(str(person.phone_numbers.values('id'))))

person_form = PersonForm(request.POST or None, instance=person)
employee_form = EmployeeForm(request.POST or None, instance=employee)
physician_form = PhysicianForm(request.POST or None, instance=physician)
email_form = EmailForm(request.POST or None, instance=email)
phone_form = PhoneForm(request.POST or None, instance=phone)

forms.update({'person_form': person_form,
              'physician_form': physician_form,
              'employee_form': employee_form,
              'email_form': email_form,
              'phone_form': phone_form,
              })



return render(request, 'UpdatePhysician.html',forms)

它不会引发任何错误，只是不显示任何内容，例如，当我键入{{person_form}} ，我会得到所需的表单。

Answer 1

您需要将表单添加到列表中：

form_list = [person_form, physician_form, employee_form, email_form, phone_form]

并将其添加到上下文字典中，在这种情况下， forms字典就是context字典：

forms.update({'forms': form_list})

然后在你的模板中：

{% for form in forms %}
    {{form}}
{% endfor %}

Answer 2

您的forms变量是dict 。 因此，您必须在模板中遍历一个数字：

{% for name, form in forms.items %}
   {{form}}
{%endfor%}

在视图中，您必须将最后一行更改为

return render(request, 'UpdatePhysician.html', {'forms': forms)
